摘要
目的探讨CT增强扫描联合三维重建技术在分化型甲状腺癌术前T分期的价值,提高CT对甲状腺癌术前评估的意义。方法搜集经手术病理证实为分化型甲状腺癌且术前行CT增强扫描的患者80例,分析术前CT增强及多种重建图像特点判断术前T分期,并与术后病理的T分期相对比,用卡方检验计算出CT增强扫描联合多种三维重建技术对甲状腺癌术前T分期的准确性、灵敏度和特异度。结果CT诊断T1期的准确性、灵敏度和特异度分别为91.3%、83.3%和94.6%;T2期的准确性、灵敏度和特异度分别为90.0%、85.7%和88.5%;T3期的准确性、灵敏度和特异度分别为96.3%、90.9%和98.3%;T4a期的准确性、灵敏度和特异度均为100%。结论 CT增强扫描联合三维重建技术有助于甲状腺癌术前T分期的评估,尤其是T3和T4a期。
Objective To explore the evaluation of CT enhancement scan with three dimensional reconstruction on the T stage of differentiated thyroid carcinoma and to improve the value of CT before surgery .Methods Images of CT enhance‐ment scan and kinds of reconstruction technology of 80 cases proved differentiated thyroid carcinoma by pathology were an‐alyzed .The accuracy ,sensitivity and specificity of T stage diagnosed by CT were analyzed by Chi‐square test ,and com‐pared with T stage confirmed by pathology .Results The accuracy ,sensitivity and specificity of T1 stage diagnosed by CT were 91 .3% ,83 .3% and 94 .6% ,respectively ,those of T2 stage were 90 .0% ,85 .7% and 88 .5% respectively ,those of T3 stage were 96 .3% ,90 .9% and 98 .3% respectively ,and all those of T4a stage were 100% .Conclusion CT enhance‐ment scan with three dimensional reconstruction technology has good performance on the T stage ,especially the T3 and T4a stage .
